Schizophyte or bacterium Il use the
word bacterium in q generic sense) or
microbe as the French would call it.
I further showed that this bacterium
is for its existence not dependent on
the organism of the hog but can live
and propagate in other media outside
Of the animal organism even in water
containing little organic mixture. 1t
was also shown that the outside media
usually constitute the vehicle by which

such vehicle IL usually sufficient to
produce the disease. It was further
ascertained that q certain length of

is usually called the period of incuba.
ton or since the infectious principle is
an organism that propagates and forms
colonies inside the animal body and
since such propagation or coloniza-
ton must take place before the NOR
bid process can become extensive or
serious enough to produce plain and
unmistakable symptoms it may be
properly calledthe stage ofcolonisation
Its length it seems depends upon the
number of germs bacteria or microbes
introduced. If the number is small
the stage Of colonization will be long
one and if large it will be short. This
I think will. not need any explanation.
OF the mode and manner Of which
and the means bywhich these microbes
invade the organism Of the hog I will
have something to say further on. Re-
cent research has demonstrated that q
great many diseases of man and beast
and even of plants owe their origin
and spreading to the presence and prop
agation of similar small organisms,
bacteria or microbes and it is not only
probable but absolutelycertain that all
infectious diseases owe their existence
to the presence of bacteria. In regard
to this great many undeniable proofs
have been given. 1t has been found
however that quite number of these
small disease producing organisms or
pathogernic bacteria cause mischief
only in amediate way that is not 50
much directly bytheir mere presence as
indirectly by their poisonous fermen-
tive products the so called ptomaines
while others il seems cause.-the morbid
changes Of the disease which they in
duce in a direct immediate way by
their presence and not by producing
ptomanies. The germs Of swine
plague 1t seems belong to the latter
class while the germs of bacteria of all
those diseases in which decomposi-
ton of the blood constitutes one Of the
charactistic features for instance an.
thrax black leg, Texas cattle fever
and several others probably belong to
the former. The morbid process Of
Swine Plague is best traced in the
lungs and in the simultaneous tissues
but in the lungs particularly.
